The relationship between whole blood selenium (Se) concentration and the activity of the seleno-enzyme, glutathione peroxidase (GSH-Px, E.C.I.11.1.9) in camel (Camelus dromedarius)

The concentration of Se and the activity of the enzyme glutathione peroxidase (GSH-Px) were investigated in the whole blood of camels. Variable concentrations of whole blood Se (0.025-0.043 μg/ml) and GSH-Px activity (6.32-18.64 EU/ml) were demonstrated in both sexes, with females having significantly higher (P<0.001) blood Se concentration and GSH-Px activity than males. A highly significant correlation (r=0.88, P<0.001) has been demonstrated between whole blood Se concentration and the activity of the enzyme GSH-Px.
